T all whom it may concern Be it known that I, EUCLID I. LA CHAPELLE, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invent ed certain Improvements in a Machine for Operating on Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indi- I eating like parts in the several figures.

' crating on The invention relates to machines for opshoes, and more particularly to! mechanism for shaping and smoothing the heel of a shoe about its heel seat.

The object of the invention is to provide novel and improved mechanism for smoothing and shaping the heel of a lasted shoe which is well adapted for operating upon turn shoes after they have been turned and re-lasted..

To this end the invention consists in the features of construction and combinations of parts hereinafter described and referred to in the claims.

The present invention is a division of aplication Serial No. $345042, filed May 21, 1908, and in the drawings the invention is shown embodied in mechanism applied to the jack of the leveling machine shown and described in that application.

In the drawings, Figure 1 is a side elevation showingjthe jack of a shoe leveling machine carrying devices for smoothing the heel about the heel seat of the shoe supported on the jack, which embody the invention in its preferred form; Fig. 2 is a transverse sectional view showing the operation of the smoothing hammers; Fig. 3 is a plan view showing the arrangement of the hammers; and Fig. 4 is a. detail view showing the cams for operating the hammers.

As shown in the drawings, the devices for smoothing and shaping the heel about the heel scat comprise a series of hammers or' boaters arranged to operate on the heel of a shoe supported on the jack. This series of hammers comprises a hammer 156 arranged. to opcrate upon the back of the heel, and two sets of hammers arranged to act upon the opposite sides of the heel, each set comprising two hammers 157 and 158. The hammer 150 is pivotally supported upon a rod 159 mounted in the upper end of a lever 160 and held yieldingly in advanced position in the lever by a spring 161. The hammer 18 held yieldingly in position in the end of the rod 159 by a spring 162, and the pivot for the hammer is so arranged that the operating surface of the hammer will automatically accommodate itself to the curvature of the shoe in the direction of movement upon the back of the heel close to the sole,

and to then move vertically while pressed against the shoe. By this hammering and rubbing action the back of the heel about the edge of the heel seat is shaped, and the back of the heel is smoothed and finished.

The side hammers 157 and 158 are pivotally supported on the ends of rods 16% and 165 mounted in the upper ends of two levers 166 and 167 arranged on opposite sides of the heel post 168 of the jack. The hammers are mounted in the ends of the hammer carrying rods in such manner that their working faces will automatically conform to the lateral and longitudinal curvature of the sides of the heel as the hammers engage and move over the surface of the heel. The hammer carrying rods are held yieldingly in advanced position in the levers by springs 169, and the rods are so mounted in the levers that when the lovers are given an oscillatory movement the hammers are caused to strike blows upon the sides of theheel close to the sole, and to then move vertically away from the heel seat while hold in engagement with the heel. This hammering and rubbing action shapes the heel about the heel seat and smooths and finishes the sides of the heel.

Vibratory movements are imparted to the overs 166 and 167 to move the hammers toward and from the heel, and the lovers are also given vibratory movements to vary the position of the hammers 157 and 15S longitudinally oi the shoe. so that the entire surface of the heel will be engaged and operated upon. The lever ion is pivotally supported at 170 so that its upper end may be moved toward and from the shoe supported on the jack, and may move laterally. The lower end of the lever is provided with a roll 171 engagin a cam groove 17 2 formed 5 in a cam drum 1 3, the cam groove being so formed that it imparts rapid oscillatory movements to the lever to move its upper end toward and from the ,heel of the shoe supported on the jack. The lower end of the lever 166 also carries rolls 17 4 arranged .to engage cam surfaces 175 formed on the ,ecam drum 173, and shaped to vibrate the upper end of the hammer carrying lever longitudinally of the shoe supported on the jack. The cams are so shaped that the hammers' will be shifted longitudinally of the heel of the shoe between successive blows, so that successive blows will be dealt at different points upon the heel, and thus the en- 20 tire heel will be subjected to a hammering and rubbing action by the series of hammers. The lever 167 carrying the hammers 157 and 158.for acting upon the opposite sides of the heel is actuated in the same manner by cams similar to cams 17 2 and 175. The cams for operating the hammers which shape and smooth the heel are secured upon a shaft 176 mounted in the jack' 1, and driven through a belt 177 from the shaft 2,

- which is in turn driven through a belt 178.

While the invention has been shown embodied in a shoe leveling machine, it will be understood that it is not confined in its application to such a machine, but may be embodied in machines which are not adapted for performing the leveling operation. It will also be understood that the invention is not limited to the specific construction and arrangement of parts shown and described, and that the construction and arrangement of the parts may be varied and modified as may be found desirable or best suited to the construction of the machine in which the invention is embodied.

Having explained the nature and object of the invention, and specifically described one form of machine in which it maybe embodied, What is claimed is 1. A machine for operating upon shoes,

having, in combination, a series of tools arranged to embrace the end of a lasted shoe and to act on the side of the last,'and means for actuating the tools to hammer and apply a rubbing pressure to the shoe upper.

2. A machine for operating upon shoes,

having, in combination, a series of sidehammers arranged to embrace the end of a lasted shoe, and means for actuating the hammers to deliver blows upon the upper about the edge-of the last and to move away from the edge of the last while in engagement with the upper.

3. A machine for operating upon shoes, having, in combination, a support, a series of hammers arranged to embrace the heel of a shoesupported on the support, and means for actuating said hammers to deliver blows upon the heel about the edge of the heel seat and to move away from the heel seat while in engagement with the heel.

4. A machine for operating upon shoes, having, in combination, a series of hammers arranged to operate upon a lasted shoe, means for actuating said, hammers to shape and smooth the upper about the edge of the last, and means for shifting the hammers tovary the-point of operation of the hammers longitudinally of the shoe.

5. A machine for operating upon shoes, having, in combination, a' shoe support, a series of hammers arranged to operate upon the heel of a shoe supported on the support, means for actuating said hammers to shape and smooth the heel about the heel seat, and means for shifting the hammers to vary the point of operation of the hammers longitudinally of the shoe.

6. A machine for operating upon shoes, having, in combination, a shoe support, hammers arranged to operate upon opposite sides of the heel of a shoe supported on the support, means for vibrating the hammers to deliver blows upon the heel, and means for vibrating the hammers to change the point of operation upon the heel.

7 A machine for operating upon shoes, having, in combination, a shoe support, hammers arranged to operate upon opposite sides of the end of a shoe supported on the support, means for vibrating the hammers to deliver blows upon the upper, and means for vibrating the hammers to change the point of operation upon the upper.

In testimony .whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
